Walker 285-1002 Nitrogen Oxide (NOx) Sensor - Downstream
Walker Genuine OE NOx Sensor for Ram Diesel Emissions
Walker Genuine OE NOx Sensor Part Number 285-1002 is built for precise nitrogen oxide monitoring in selective catalytic reduction systems. It is a direct-fit, downstream replacement for select 2018 Ram 2500 and 2018 Ram 3500 applications, with OE-style connectors and harness length for a clean installation.
Key Features
- Genuine OE line NOx sensor for emission control service
- Specific fit design for downstream placement
- OE connector and harness length for plug-and-play replacement
- Built with Tier 1 OE supplier materials and manufacturing standards
- Gray female connector, oblong shape, 4 terminals, blade terminals
- Matte finish with multi-colored sensor body
- Wiring harness length: 590.00
Product Details
Walker Products Genuine OE NOx Sensors are engineered for diesel and gasoline emission systems that rely on accurate exhaust gas monitoring. On 2018 Ram 2500 and Ram 3500 downstream applications, Part Number 285-1002 helps the SCR system measure NOx levels so the aftertreatment system can operate correctly and protect downstream components such as the diesel particulate filter. Walker’s OE-focused design supports direct replacement service with the connector style and harness length matched to the original layout.
The Genuine OE product line from Walker is aimed at replacement parts that follow original equipment specifications for fit, electrical connection, and sensor performance. For Ram 2500 and Ram 3500 owners servicing a downstream NOx sensor fault, 285-1002 provides an OE-level replacement path without requiring custom wiring or connector changes.
What This Sensor Helps Address
- Check engine lights related to NOx sensor faults
- Incorrect NOx readings in the SCR aftertreatment system
- Reduced diesel emission system efficiency
- Aftertreatment issues that can affect DPF protection
- Drivability concerns tied to emission system diagnostics
Installation Notes
Fits 2018 Ram 2500, downstream. Fits 2018 Ram 3500, downstream. Confirm the connector shape, terminal count, and harness routing against the original sensor before installation. This is a specific-fit sensor, so it is intended for the listed application only. Part Number 285-1002 is a direct replacement for the downstream position on these Ram models.
Quality Assurance
Walker states that its Genuine OE NOx Sensors are produced by Tier 1 OE suppliers and built to the same material and manufacturing standards used by leading vehicle manufacturers. The sensor is field-proven for harsh exhaust environments, including heat, vibration, and corrosion. This part cross-references no additional part numbers in the provided data.
